Abstract

SARS-CoV-2 infection has been divided by scientific opinion into three phases: the first as asymptomatic or slightly symptomatic and the second and the third with greater severity, characterized by a hyperinflammatory and fibrotic state, responsible for lung lesions, in some cases fatal. The development of antiviral drugs directed against SARS-CoV-2 and effective vaccines is progressing; meanwhile, the best pharmacological objective is related to the management of all the complications caused by this viral infection, mainly controlling the inflammatory and fibrotic state and preventing the infection from moving into the most serious phases.
